G sharp (enharmonic A flat).
E-sharp.
The leading tone in the key of D, whether major or minor, is C#.
Yes it uses the whole tone scale as there are no semitones in the melody. You are right.
fa also kmown as f
F♭ major is a theoretical key, since the B note requires a double flat to keep the TTSTTTS major scale formula straight (in this case T = tone, S = semitone).The scale goes as follows:F♭, G♭, A♭, Bbb (double-flat), C♭, D♭, E♭ and F♭.Bbb is the enharmonic of A♮.The relative minor of this scale would be D♭ minor and the enharmonic equivalent is E major (with the significantly simpler key signature of four sharps).
The leading tone is the seventh scale degree of the diatonic scale which in F Major is the note "E".
The leading tone in a scale is one half-step below the tonic. In the key of C# major, the leading tone is B#.
The leading tone is the seventh note in the scale. For D-flat major, this would be C.
resolution
The leading tone in a key is one half-step below the tonic. In the key of A major, the leading tone is G-sharp.
E
E#
The leading tone is one half-step below the tonic, so in the key of B-flat the leading tone is A.
B-flat
G sharp (enharmonic A flat).
F sharp is the leading note (7th degree) of the G major scale.
C is the leading tone in the Key of D.
